Volumio as HDMI splitter?

If I plug an HDMI device into my RPI running Volumio, can it act as an HDMI audio splitter and send the audio to my hifiberry Digi+ that connects to my hifi over coax?

I want to connect a Chromecast to my hifi, so I’m trying to determine if I’ll need a separate HDMI audio splitter, or if Volumio can do that for me.
